ROTARY BRUSH.`

SPECIFICATION forming part of Letters Patent No. 583,299, dated May 25,1897.

Application tiled November 16, 1896. Serial No. 612,349. (No model.)

To all whom t may concern:

Be it known that I, THOMAS BROWN, residing at Lincoln, in the county ofLancaster and State of Nebraska, have invented a new and Improved RotaryBrush, of which the following is a specification.

My invention relates to improvementsin rotary brushes and means foroperating the same, and more particularly refers to that class ofbrushes designed for barbers use, such invention primarily having forits object to provide a barbers rotary hair-brush of a very simple andeconomical construction and which can be easily manipulated.

It also has for its object to provide a brush of the character statedhaving a shield and simple means for attaching the saine to the brush.

Vith other obj ects in View, which will hereinafter appear, theinvention consists in a rotary brush embodying the peculiar and novelfeatures of construction hereinafter first described in detail and thenspecifically pointed out in the appended claims, reference being had tothe accompanying drawings,in which- Figure 1 is a perspective view of myinvention. Fig. 2 is a longitudinal section of the same, the spiralhandle members being at their innermost position in full lines andpartly drawn out in dotted lines. Fig. 3 is a transverse section takenon the line 3 3 of Fig. 2. Fig. 4 is a detail view illustrating themeans for detachably connecting the lower end of the shield-supportingrod on the handle members.

Referring to the accompanying drawings, in which like numerals indicatelike parts in all the ligures, 1 indicates the stock or body portion,and 2 the bristles, which are secured to the stock in any well-knownmanner. The body portion 1 has acentral bore 3 extended longitudinallytherethrough and of uniform diameter, such bore terminating at the endsin enlarged annular seats 4C, in which are tixedly held metal disks ornuts 5, which have central apertures having spiral screwways 6, thescrewways in the washer at one end being arranged in an oppositedirection to that of the screwways in the washer at the other end.

8 indicates the handle members, which have extensions 9, provided with aseries of spirally-arranged threads which are adapted to engage thespiral ways in the nuts 5, the said spiral ways of one handle extendingin the direction reverse to those in the other handle. It will benoticed by reference to Fig. 2 that the spiral extensions of the handlemembers are of a less diameter than the lbore ofthe body l, so as tomove freely within such bore, the ends of such spiral members, however,having smooth head portions 10, which fit the bore and form bearingportions for the inner end of the spiral extension and serve as anadditional journal portion for the body to turn on, which body has itsmain bearing on the spiral extension at the points where the nuts 5engage the same.

So far as described it will be readily seen that by providing the handlemembers with spiral extensions of reverse pitch that such handle memberswill serve the double purpose of forming the supporting means and alsothe means for imparting a reverse rotary motion to the brush, it beingobvious that by pulling the handle members outward the brush will berotated in one direction, and by forcing the handle members inward thebrush will be rotated in a reverse direction, the speed of such rotationbeing governed bythe pitch of the spiral threads on the handle members.The headed portion of the spiral extension also forms stops to limit theoutward pull on the handle members as they engage the washers, and suchhandle members are drawn ont to their fullest extent.

11 indicates a shield which is detachably connected preferably to thehandle members by means of` pendent rods 12, pivotally connected attheir upper ends to the four corners of the shield and at their lowerends detachably connected to the handle members, such connection beingof such a-nature as to permit the shield being readily detached whendesired. For this purpose each handle member has a band 13 clampedthereto, each of which is provided with a pair of transverse sockets 14,adapted to receive the angle portions l5 of the rods, which are adaptedto be slid into such sockets, in the manner clearly shown in Fig. a. Byproviding such means of connection it is obvious the shield will be heldto a iixed position-that is, from swinging around during the operationof rotating the brushthe pivotal connection of the han- TOO admit of thedischarge of the collection in the said pockets. By thus connecting` theshield to the handle members the same can be quickly removed from orattached to the brush. From the foregoing description, taken inconnection with the accompanying drawings, it is thought the advantagesof my invention will readily appear. The same 1s of a very simplenature, can be manufactured` at minimum cost, is easily operated,durable and eiiicient, and not liable to get out of order.

Modifications in details maybe resorted to without departing from thescope of the appended claims.

Having thus described my in venton, what I claim, and desire to secureby Letters Patent, is

1. A rotary brush comprising a bristle-carrying body handle membershaving spiral extensions movable longitudinally in the ends of the bodyportion and spirally-threaded nut members ixedly connected to the bodyto engage the spiral extension of the `handle members substantially asshown and deseri-bed.

2. A rotary brush comprising a body portion, handle members havingportions end- Wise movable in the said body, said extended portionshaving spiral threads, `theispirals on one handle extending in a reversedirection to those on the other handle, nui. or disk members havingspirally-threaded apertures held to engage the spiral portions of thehandles and xedly connected with the brush-body as specified.

3. The combination With the brush-body, the endWise-movable handle,having spiral extensions and the spiral nuts carried by the brush-body,of a shield having extensible connectin g members adapted to be securedto the handle members as specified.

4. The combination with the brush -body having a longitudinal bore andthe Washers at the ends of such bore, having spirallyf threadedapertures of a diameter less `than that of the bore, of thehandlemembers'havin g spiral extensions to engage the Washers, andheaded portions at their inner end to fit the bore of the brush-body asspecified.

5. The combination with the brush-body havin g a central boreterminating at theends, spirally threaded Washers and the handle members`having spiral extensions movable through the washers, said handleAmembers having bands provided with transverse sockets, of a shieldhaving `pendent rods at :the ends pivotally connected therewith, saidrods having angle members adapted to :lit said sockets substantially asshown and described.
